CASH AND' PARCEL CARRYING SYSTEM..

SPECIFICATION forming part of Letters Patent No. 295,172,dated March 18,1884.

v Application led February (i, E84. (No model.)

To ali.'- wiom t may concern,.- y

Be it known that I, WARREN S. HILL, of Boston, in the county of Sut''olkand State of Massachusetts, have invented a new and useful ImprovementinCash and Parcel Carrying Systems, which improvements are fully set forth in the following specification.

My improvement relates to a eash-carrying system wherein is employed acar running on a wire way, and has especial reference to the mechanismemployed to stop and retain the car when it has rear-.hed tlleend of itsrun.

It consists of a buffer and a retaining device secured to the wire way,about which itis disposed axinlly,so that the wire passes through its'center, and a hooked arm or lever pivoted to the ear and held'against astop by a spring, by means of which it is kept in position to engagewith the retaining-flange oft-h e butter, all et' which will be moreparticularly described hereinafter. i

Referring to the drawings, Figure l reprej sents a side elevation,showing the different parts in position when the car has reached the endoi' its run and is secured to the buffer. Fig. 2 shows the hooked armmade integral with the handle for throwing the oar along the wire, andthe stop that keeps itin position to engage with the buffer. Fig. 3 isalongitudinal Vertical section, showing the construction ci' the buffer,and its relation to the wire way and to the parts shown in Fig. 2. Fig.4 shows another form in which the buffer may be made.

In the drawings, A. represents a ear, the grooved wheels ot' which, da,run on the wire B. O is the butter, through which the wireB passes, andto which is secured the clamp c ci. The @entrai piece of the frame, c',has its ends extended beyond the uprights that carry the grooved wheels,land a 'projection on its upper side, c2, (see Fig. 2.) is grooved tobestride the wire B, and forms what may be termed a butter end,77 n?. Asthis is the part that strikes theprojeeting end ot' the buffer, asomewhat similar projection extending downward, c3, receives the pivotedarm D, the pivot being shown at d. riihe hooked end d? is shaped so asto readily slide over thebeveled edge of liangef' on the buffer whenthey come together. The arm D lmay be made integral with the handle di,by which the car is 'thrown along the wire'. A projection, d, on

` the top of the arm D has a bearing on the frame a', as shown at a,against which it is held by a spring, g, thereby forming a stop, bymeans 'of which the arm D is held in position to engage with the iiangef of the buffer. The spring g is secured to the-stop d and to the framea at a5. The buffer G is i u two partsone fixed and the other movable.The fixed part c has a lug, c', at its outer end, and a. strap, ci, issecured to it by two screws, only one of which, ci, is shown in thedrawings. The wire B is clamped between the lug c and the strap c2,thereby securing the buffer to the wire without danger of injury to thewire, as would be the case were a set-screw employed. The movable partof the buffer,f, is fitted to move on the extended cylindrical part ofc. 1t has a fiange, f', which acts as a catch for the hooked arm D.- Agroove, f2, receives the pin c4, which limits the outward movement of 'Awasher, f3, of leather or other material, 'may be fitted into a recess'in the end of f, to lessen the noise when the parts come together. Thebuffer spring 7L is placed between the ange c5 ofthe fixed part c andthe iiangef of the movable part, and when the ear strikes the buffer itsmomentum is received by the spring h as the movable part f is pushedtoward and onto the fixed part c, and the yielding of the spring bringsthe ear to a gradual stop, the reaction of the spring bringing the partsagain into their normal position.

The operation of my invention is thus (iescribed: As the car A comestoward the but'- `fer C, the hooked arm D is, by means of the stop d andthe spring g, held in position so that the inclined surface of the hookd2 strikes the beveled edge of the retaining-tiangef, and by theyielding of spring g slides over it, and the car and buffer becomelocked together at the instant of contact between the buffer end ofthecar, c2,and the projecting end ofthe buffer, f3, and both move forwardtogether until the inertia of the ear is overcome by the resistance ofthe buffer-spring h, when the recoil of the spring restores the parts totheir normal position again. Theear ispropelled along the wire `B by thehandle da, which is pivoted to the car by being made integral with thearm D, and a slight pressure on the handle in the IOO direction the caris to be sent releases the hook d`l from the retaining-flange f', andthe car is' easily throi'vn along the wire B.

Having` thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, isy 1. Ina cash and parcel carryingsystem, a car provided with a pivoted hooked arm held against a stop bya spring, and a lbuffer dis posed axilly on the Wire way` consist-ing ofa xrd part secured to the Wire7 and a yielding pait moving againstaspring, and having a retaining-flange t'o engage with the pivoted`hooked arm, substantially as set forth.

2. In a buffer for a cash-carrying system, the combination ofthe fixedpart c, with lugv c', strap cscrcws c3', and pin c, and the movablepartf, with retaining-Heilige f, slot f2, washer f3, and the springll,"substantially as shown and described.

3. In a cash-carrying car7 the combination of the handle d, madeintegral with the pivoted hooked arm D, the stop d, spring` g, and framea,substantially as shown and described.

In testimony that I claim the foregoing; as my ovvli invention Ihereunto affix niy signature in presence of two witnesses.
